My invention relates to water heaters, and particularly to stock tank heaters.

The principal object of my invention is to provide an improved, simplified, and durable stock tank heater for heating the drinking water supplied to farm live stock, although it may be employed for other suitable purposes. Another object of the invention is to provide a stock tank water heater of novel sheet metal construction in which the heater body is composed of a horizontal heater, or burner, section and an inclined section connected therewith, the latter having a separate air conduit therein for supplying air to the burner.

A third object is to provide a stock tank heater of novel sheet metal construction in which the heater body is composed of a horizontal heater, or burner, section and an inclined section connected therewith, the former being made of three pieces of. sheet metal and the latter having a two part separate air conduit unit removably mounted therein for supplying air to the burner.

Other and more specific objects of the invention are mentioned and described herein.

The invention is illustrated in the accompanying drawing, wherein Figure 1 illustrates my improved tank heater arranged in a water tank;

Figure 2 illustrates a longitudinal section taken through the heater unit, very much enlarged;

Figure 3 illustrates a section taken on line 33 of Figure 2;

Figure 4 illustrates a sectional view of the check valve for the fuel supply pipe; and

Figure 5 illustrates a section taken on line 5-5 of Figure 2, omitting the bottom wall of the heater body.

Similar numerals of reference indicate like parts throughout the several views on the drawing.

Referring to the details of the drawing the numeral l indicates a stock water tank within which my improved stock tank heater is removably arranged. The body of my improved tank heater, which may .be rectangular in cross section, and which preferably is made of sheet metal, may comprise the heater, or burner casing section 2 and the inclined air conduit casing section 3, the latter being upwardly inclined to project above the surface of the water contained in the tank I.

The heater body, as illustrated, is preferably made from three pieces of sheet metal 4, 5, and

. 6, respectively, in which construction the piece or part 4 is formed trough-like, or channelled,

and bent at I to provide the bottom wall 8 and opposed side walls 9 and ill of the body section 3, and providing also bottom wall H and side walls l2 and I3 (one only being shown) of the burner casing section 2.

In this construction the side walls I2 and i3 are extensions of the side walls 9 and I0, respectively, and the bottom wall II forms an integral extension of the angular bottom wall 8. The heater body piece 5, which is bent at M, constitutes the top wall for both casing sections 2 and 3 and has its marginal edges welded, or otherwise secured, to the upper edges of the side walls 9 and iii of body casing 3 and also to the side walls 52 and E3 of the body casing section 2.

The sheet metal piece or part 6 forms the end wall for the burner casing section 2 and has its marginal edges welded, or otherwise secured, to the adjacent side walls i2 and I3, bottom wall H and top wall 5 of the burner casing section, whereby a watertight body unit is produced. The numeral I5 indicates a plurality of transverse Water circulating flues terminally secured in the side walls ii and I2 of the casing section 2 to conduct Water therethrough. A vent pipe or chimney it may be mounted upon the burner casing 2 over a suitable opening to place the interior ofv said casing in communication with the outer atmosphere.

The numeral I! indicates an inverted troughlike, or channelled, air conduit removably arranged within the body casing 3 and upon the bottom wall ll thereof, the lower end of said air conduit cooperating with the open end of the inverted air conduit l3 which is arranged removably within the casing section 2 and upon the bottom wall thereof. One end ill of the conduit section i8 is permanently closed. Preferably, there is effected a telescopic sliding connection between the conduit members I1 and iii to facilitate the passage of air therethrough to the burner hereinafter mentioned, such telescopic connection being facilitated by a guide finger 26 mounted upon the lower end of the conduit mem ber i'i'.

A pair of opposed angle iron guide and retainer pieces 2| are secured to the side walls 9 and ii] to maintain the juxtaposition of the conduit member IT. A fixed stop element 22 may engage the end wall of conduit member ill to maintain the latter against longitudinal displacement and in the proper relation with the conduit member IT.

The top wall of the conduit member I8 is provided with an air outlet opening 23 to conduct air supply to the liquid fuel burner 24 which is carried by the elbowed fuel supply pipe 25 which is connected with a ball check valve 26. Numeral 21 indicates a fuel supply elbow connected with the valve 26, said elbow being provided with a pair of opposed brackets 28 which are rigidly fastened to the top wall of conduit member 3 by the bolts 29, (Fig. 5), whereby the burner unit 24 and valve 26 are supported and maintained in operative position in relation to the flues l5. 7

The numeral 36 indicates an arcuate air baflie mounted upon the conduit l8 adjacent the opening 23 to facilitate the direction of air to the burner 2 A fuel supply pipe 3i is connected with the elbow 2'! to supply liquid fuel to the burner from a container 32 which may be under the control of a needle valve 33. The upper end of the air conduit Il may be permanently open,

\ and a cover 3 1 hinged at 35 may function to close the remaining open end of the casing section 3.

I claim:

1. A stock tank heater comprising a burner casing section, an inclined air conduit casing section permanently connected therewith, said burner casing section having a plurality of water circulating flues mounted therein, a two part air conduit removably arranged within the burner casing and air conduit casing sections, the outer part of said air conduit comprising an inverted channelled member, a liquid fuel burner mounted within said burner casing section, means for supplying liquid fuel to said burner, a vent pipe for said burner casing section, and a closure for the upper end of said air conduit casing section. 2. A stock tank heater comprising permanently connected burner casing and air conduit casing sections forming a heater body, said body being formed from three pieces or parts of sheet metal, of which the main part is trough-like in formation to provide bottom and side walls for said two casing sections, the other two parts of said body forming the top wall for both of said casing sections and the end wall for said burner casing section, a plurality of water circulating flues' mounted in the burner casing section, a liquid fuel burner mounted within said burner casing section relatively to said fiues, means for supplying air tov said burner, and means for supplying liquid fuel to said burner.

3. A stock tank heater comprising a burner casing section, an inclined hollow casing section connected therewith, a separate air conduit section arranged within said inclined section and extending into said burner casing section along the bottom wall of the latter, a liquid fuel burner mounted upon the lower end of said air conduit and adapted to receive a supply of air from said air conduit.

4. A stock tank heater comprising a burner casing section, an inclined hollow casing section connected therewith, a separate channelled air conduit section arranged within said inclined and burner casing sections and upon the bottom wall of the latter, said air conduit being provided with an air outlet opening, a liquid fuel burner mounted upon the lower portion of said air conduit adjacent said air outlet opening, and a plurality of transverse water circulating flues mounted in said burner casing section.

5. A stock tank heater comprising a burner casing section, an inclined hollow casing section connected therewith, said burner casing section having a plurality of water circulating fiues mounted therein, a two part channelled air conduit removably arranged within said burner and inclined casing sections, one part of said air conduit being arranged upon the bottom wall of said burner casing section and provided with an air outlet, a liquid fuel burner mounted upon said air conduit section which is provided with the air outlet and adjacent the latter, said fuel burner being removable with said air conduit, a plurality of water circulating fiues mounted in said burner casing section, and means for supplying liquid fuel to said burner.
